5- a 1 (ga /4' g g Patented Apr. 21, 1931 PATENT OFFICE GEORGE M.SCHAFF, 0F CLEVELAND, OHIO SHOE Application filed June 14,

The invention relates to cushioning and arch supporting means for thesole of a foot when inclosed in a shoe and inter-locking means therefor,preventing the shifting of the parts, thus permitting the foot to restnaturally at all times thereon and preventing injurious strain upon thefoot by the displacement of any part.

To accomplish these and other valuable objects, the invention comprisesthe combination and arrangement of parts and manner of constructing thevarious details, hereinafter described, illustrated in the accompanyingdrawings and specifically pointed out in the claims.

In the accompanying drawings, Fig. 1 is a vertical longitudinal sectionof a shoe showing the outsole and heel, a longitudinal metal archsupport, an insole and a heel cushion interlocked together by theimproved method; Fig. 2 is a similar view showing the above mentionedparts with the addition of a cushioned insole, between the regularinsole and the heel cushion; Fig. 2a shows a modified type of attachedlocking pin.

Fig. 3 is similar to Fig. 1 showing a metatarsal pad or cushion appliedto the insole; Fig. 1 is a plan of a sole showing a metal arch supportsuperimposed thereon and interlocked therewith and having lateralextensions; Fig. 5 is a similar view showing the arch support having onelateral extension; Fig. 6 is a similar view showing the arch supporthaving a broadened inner edge; Fig. 7

is an edge elevation thereof; Fig. 8 is a plan of an insole showing theheel cushion superimposed thereon and interlocked therewith; Fig. 9 is aplan of an insole showing the heel cushion, and a metatarsal padsuperimposed thereon; Fig. 10 is a side elevation thereof; Fig. 11 is aplan of the heel cushion; Fig.

11a is a side elevation of the same; Fig. 12 is a side elevation of ashort metatarsal plate, and Fig. 18 is a plan thereof; Figs. 14 and 15are plan and side elevations respectively of a metal plate for aflexible shank shoe.

In these views, in Fig. 1, A represents a unitary structure of outsoleand heel, B is the metal plate for supporting the arch of the foot, C isthe insole and D is a cushion posi- 1929. Serial No. 870,776.

tioned to absorb the shock upon the heel in walking,

The heel A, metal plate B, and insole G, are provided with the alinedopenings A, B, and C, respectively and the cushion D is provided with avertical locking pin D which may be integrally formed from a downwardlyprojecting portion of the substance of the fabric, or may be formed ofan attached pin of metal or other substance as shown in Fig. 2a, toserve as a lock member, to secure all these parts in close contact witheach other, so that they are substantially immovable in the shoe.

If the locking pin is composed of felt it may be reinforced by metal asshown at D6. The lower extremity of the locking pin is preferablylaterally expanded to form a head at D2 thus preventing the accidentalwithdrawal of the pin from the opening A in the heel, which is alsoexpanded at A2 to receive the same.

The arch support B preferably extends to the ball of the foot, and maybe laterally eX- tended as at B2, shown in Figs. 4 and 5, or widened atthe outer end at B3 as shown in Fig. 6. This plate may be corrugated asshown at B4 to reinforce the same.

, -When this plate is provided for a flexible shank shoe it may be muchshortened as shown in Figs. 14 and 15.

The insole C may be of any regular construction as shown in Fig. 1, ormay be covered with a second insole or plate G having a pad underneaththe metatarsal joint as shown in Fig. 3 or may be covered by means of acushion inner sole E as shown in Fig. 2, if desired. Thisinner sole isalso provided with the opening E through which the pin D2 p'asses,"thusbinding the inner parts together and to the heel.

The combination of insole and heel cushion D is shown in Fig. 8 and thecombination of insole 0, heel cushion D and metatarsal pad C2 is shownin Figs. 9 and 10 and the pad is covered with a coating of fabric C3.

The cushion D and its locking pin D, provided With a head D2, are shownseparately in Figs. 11 and 11a.

' In Figs. 12 and 13a separate short metaa'meta'l' arch su'pport thereonhaving a eorre tarsal plate or insole F is shown provided with theopening F and a. pad F2. Other variations in assembly of the variousinner parts can be made at will by substituting one inner part foranother, to suit the requirements of the feet of the wearer.

All the inner parts are locked together and t0 the heel by means of thepin D, which may be attached to, or formed integrally with the heelcushion D.

In Fig. 2a a metal tubular pin D3 is provided with an attaching base D4.Other modifications may be made within the spirit of the invention, andscope of the claims.

Having described the invention what I claim as new and desire to secureby Letters Patent is:

1. In a shoe the combination with a continuous heel and sole, of a metalarch supporting plate, an insole and a heel cushion superimposedthereon, said heel, plate and insole being provided with registeringopenings, and a locking pin passing downwardly through said openings,said pin being attaclllled to'said heel cushion and movable therewit 2.In a shoe a continuous sole and heel, a metal arch support thereover, aninner sole and a metatarsal pad and heel cushion superimposed thereon,said heel, metal arch support, inner sole and metatarsal pad havingregistering openings therein, and a locking member projecting downwardlyfrom said heel cushion and passing through said arch support and innersole.

3. In a shoe a continuous sole and heel, a metal arch support thereover,an inner sole and a metatarsal pad and heel cushion superimposedthereon, said heel, metal arch support, inner sole and metatarsal padhaving registering openings therein, and a locking member projectingdownwardly from said heel cushion and passing through said arch supportand inner sole, said. locking pin being laterally expanded at its lowerend and the opening in said heel being correspondingly expanded.

4. In a shoe a continuous sole and heel, said heel having a verticalopening therein, an arch supporting plate and an insole thereon, andaheelcushion thereover, said plate and insole having vertical openingstherethrough registering with the opening in said heel, said cushionbeing provided with a locking member passing through all said openings,said plate being provided with reinforcing means and with lateralextensions substantially as described.

5. In. a shoe a sole and a heel, said heel having a vertical opening inits upper face,

spending; opening, a covering member for said arch support having acorresponding opening, a heel cushion superimposed there- 011,,and-a.locking member secured to said heel cushion, said locking member passingdownwardly through all said openings and engaged with said heel.

In testimony whereof I affix my signature.
